With multi-VRF (Virtual Routing and Forwarding) support, all Layer 3 multicast protocols operate as separate instances, per VRF, depending on the VRF-specific multicast configuration. All the required configuration and mcast routing tables have multiple instances, per VRF, and function simultaneously, allowing network paths to be segmented without using multiple routers.
Multi-VRF supports multiple instances of Layer 3 multicast protocols on the same router at the same time. When IPv4 PIM is enabled globally, you can configure various options for IPv4 multicast over multi-VRF, such as the rendezvous point and the PIM hello interval.
